Your edge on race day

Course-Aware AI

Trained on the actual GPX data. It knows what's coming before you do and adjusts your pacing for hills, flats, and downhills in advance.

Live AI Coaching

Claude or ChatGPT coaches you in real time through your AirPods. Adapts to your pace, heart rate, and how the race is going.

Heart Rate Guard

Streams live heart rate from Apple Watch. Warns you before you redline. Tells you to ease off before the climb at mile 10 wrecks your race.

Smart Splits

GPS-tracked pace with elevation context. Knows when a slow split is actually smart pacing on an uphill, not a sign you're fading.
